An electronic cigarette atomization device includes an atomization bushing, an electric heater coil and an atomization base located in the atomization bushing. The atomization device further includes a liquid supply component inserted into the atomization bushing; the liquid supply component is formed by high temperature resistant fiber free of glass fiber and, a through hole axially extended is defined in the middle portion of the liquid supply component; and the electric heater coil is positioned in the through hole of the liquid supply component and is pressed against an inner wall of the liquid supply component. The liquid supply component of the atomization device is made of high temperature resistant fiber material free of glass fiber, thus making the construction and process simplified, leading to low fabrication cost, and causing no damage to human body.
